Series resonance (also known as series resonance withstand voltage device) is mainly used in various industrial companies with high energy and high voltage, such as power, metallurgy, and petroleum. Its technical requirements are very high, and people who have not been exposed to these aspects generally do not understand what series resonance is. However, this has not hindered the increasing development of series resonance. Its development prospects are also infinitely promising.
Because a few years ago, there was no series resonance. If you want to test high capacity and high voltage, basically everyone is in a helpless state. Because this is a very complex and dangerous job, and the instruments that could be used for measurement at that time were relatively large, bulky, and difficult to operate. And it is precisely because of the birth of series resonance that there is no need for the human body to approach when conducting high-capacity and high-voltage measurements, which greatly improves the safety of testing. Moreover, the series resonant device is small in size, light in weight, and easy to operate. Basically, only employees with corresponding knowledge can operate it. Moreover, this small machine can accurately test the high capacitance and high voltage values that need to be measured. It is precisely because of this that series resonance is widely sought after by people and has become a device purchased by major enterprises.
It can be said that series resonance, especially variable frequency series resonance, has almost saved us from the helpless state when facing the measurement of capacitor voltage. In the future development, the technological devices developed through series resonance will become increasingly abundant, so the future prospects of series resonance are limitless. After all, its emergence has solved many problems for humanity. The once helpless measurement can now be solved by using a series resonance device and following the instructions for measurement. Other measurement operations may also change in the future due to the updates of series resonance.
